My general philosophy: apply to everyone regardless of what time they are looking for. It's how I got the call a long, long time ago. Most of the new hire classes right now are in 300-400 hour range, and they are having trouble filling them. They seem to be firm mostly on their ME time. Just make sure you can hack it on Ramen noodles for a year.
I agree with mohaupt on ASA's future. Most other regionals are having so much trouble filling their own flight decks, I don't know how they are going to account for ASA's 200+ flights a day if they were to go away.
